✅+108.3% larger total L3 cache (25 MB vs 12 MB).
✅Newer platform on LGA1700 with DDR5 support instead of LGA1151 and DDR4.
✅100+% more PCIe lanes (20 vs 0) for storage and expansion-heavy builds.
✅Integrated graphics onboard with Intel UHD Graphics 770, while Xeon E-2226G needs a discrete GPU.

Trade-offs

❌Launch MSRP is still $409 MSRP, while Xeon E-2226G mostly shows up through inconsistent older-market listings.
❌56.3% higher power demand at 125W vs 80W.

Xeon E-2226G

2019

Why buy it

✅Draws 80W instead of 125W, a 45W reduction.

Trade-offs

❌Worse for gaming: lower average FPS than Core i7-12700K across 50 shared CPU benchmark tests.
❌Lower PassMark (11,174 vs 34,347).
❌Smaller total L3 cache (12 MB vs 25 MB).
❌Older platform position on LGA1151 with DDR4, while Core i7-12700K moves to LGA1700 and DDR5.
❌No integrated graphics, while Core i7-12700K can still boot and troubleshoot without a discrete GPU.
